Combined Cycle Power Plant Fundamentals, June 29-30, 2020

This course on HRSG Fundamentals is intended for those that want to know a little bit more about the HRSG and its use in combined cycle and cogeneration plants. Topics to be covered include types of HRSGs, heat exchangers, boiler circulation systems, components, heat management, controls, water chemistry, emission controls, associated equipment, and fabrication/construction. Key features include heat transfer, surface arrangements, design/operating considerations, and integration with combined cycles and cogeneration equipment. Steam conditions will also be discussed.

Learning Outcomes

  • Explain heat transfer and flow within HRSG
  • Describe the function of the economizer, evaporator, superheater, reheater, and steam drum components
  • Discuss saturated and superheated steam fundamentals, temperature and superheater controls
  • Identify purpose of drains, vents, and safety valves
  • Outline HRSG controls and protective trips
  • Review HRSG construction
